title: [The presence of t(14;18) chromosome translocation in various types of diseases].
abstract: Chromosome translocation of t(14;18) can be detected in most cases of centroblastic/centrocytic follicular lymphomas. They are causative factors of lymphomas but the translocation is present in different other types of diseases although the translocation does not belong to the features of these illnesses. Our present work shows the appearance of t(14;18) translocation in lymphocytes of two patients of Sjögren's syndrome, one that of Whipple disease as well as one of healthy donors' lymphocytes using polymerase chain reaction technique presented in one of our previous publication. The translocation occurred in the mbr of bcl-2 gene in all cases showed and the bcl-2 gene was coupled with the immunoglobulin heavy chain gene. These results are definitively positive concerning the fact of translocation as it has been proved by sequencing of the amplification products showed in our earlier and present paper. Because relatively high percentages of Sjögren's syndrome patients develop later on lymphoma, the early detection of the translocation could result in a more successful diagnosis as well as treatment of the disease. The question arises, however, what role the translocation plays in illnesses such as the Whipple disease or what kind of consequences can be drawn from the appearance of the t(14;18) translocation in lymphocytes of healthy donors.
